Occasional support (1/3) here : autofill sucks hard !

I used to play support when i felt like it ( more than 1/3 of my games, I love thresh ) but i don't like at all to be told when by autofill. Now i only play other roles since i can get support imposed on me anytime with autofill anyway. Sucks. Being autofill protected after a support game doesn't change shit since i feel I play support only to secure next game. Now every time i am autofilled support i play support reluctantly and end up playing poorly whereas it was my best role before. Sucks. I am thinking about not playing anymore every time i see autofill.
